It would be unprecedented in the satellite era and even in the past century to have a hurricane season with no hurricanes. In the past century (1926-2025) the fewest number of hurricanes in a season is two, and that happened in 1930, 1982, and 2013.

What might global fossil CO2 emissions do in 2026? Based on IEA estimates, fossil CO2 emissions could decline 0.5% in 2026. A big 2.4% drop in oil & small 0.5% drop in gas, is partially offset by a 1.2% increase in coal. All very uncertain! www.energiogklima.no/nyhet/hormuz...
